SPECIPICATION forming part of Letters Patent No. 391,337, dated October 16, 1888.

I Application filed June 7, 1888. Serial No. 276.335. (No model.) Patented in England January 14, 1887. No. 602.

To aZZ whom it may concern:

Be it known that we, ROBERT ANDREW RoBER'rsoN and J oHN GEORGE HUDsoN, both of the firm of Mirrlees,Watson and Company, Scotland Street Iron Works, Glasgow, in the counties of Lanark and Benfrew, North Britain, engineers, have invented Improvements in Cane-Mills, for which we have obt-ained Letters Patent in Great Britain on the 14th of January, 1887, numbered 602,) of which the following is a specification.

This invention, which relates to improvements in the construction of milis for expressing juice from sugar cane or analogous saccharine plants, has reference to that class of milis in Which two or more pairs of rollers are arranged in such a position that a line drawn through the axis of each pair of rollers is parallel to a similar line drawn through the aXes of the other pair or pairs of rollers.

The present improvements relate especially to the gearing by which the rolls of milis so arranged are connected and driven, and for this purpose a shaft is carried either above or below the framing and provided with a pinion of equal diametcr at each side of the mill. Each pinion drives a train of gearing so arranged as to connect the top roller of one pair with the bottom roller of the next pair, and so on, the top and bottom rollers, respectively, of each pair being connected with the opposite trains of gearing.

Mills constructed according to these improvements may be placed horizontally,.but by preference they are arranged inclined, in order that the passage of the crushed cane from one pair of rollers to the succeeding pair may be aided by gravity.

Figure l of the annexed drawings is an end view of a four-roller sugarcane mill constructed in accordance with these present improvements. Fig. 2 is aside view of the same.

In the mill illustrated by these drawings the pairs of rollers A and B and O and D are carried in an inclined framing, E, and two such pairs of rollers only are shown as being sufficient for the purpose of illustrating this invention; but it is to be understood that more than two pairs of such rollers may be used. The shaft F below the framing is the drivingshaft, and carries at its ends the pinions G and H, respectively. The pinion G gears into the toothed wheel I on the lower roller, B, of one pair of rollers, which again gears into the toothed wheel J of the upper roller, C, of the other pair of rollers, while the other pinion, H, gears into the lower toothed wheel, K, on the axis of the lower roller, D, which again gears into the toothed wheel L of the upper roller, A.

The cane may be fed into the machine in the usual manner by a chain carrier, and as the trash leaves the second pair of rollers. C and D, it may be carried away by another chain carrier, as shown by the dotted lines in Fig. 1.

It is to be understood that when more than two pairs of rollers are used the toothed wheel on the lower roller of one pair of rolls gear-s with the toothed wheel on the upper roller ol' the next pair of rolls. and so on continuonsly for any number of pairs of rolls.

By means of the improvements constituting this invention the trash-turner or its equivalent, commonly employed and necessary in the ordinary three-roller Sugar-cane mill, is dispensed with, and the small pinions commonly employed in such mills replaced by the larger toothed wheels employed in connection with these improvements.

We clanu- The combnation, in a cane-mill, of a pair of rollers, A and B, a lower pair of rollers, G and D, driving-shaft F, arranged between and below said pairs of rollers, pinions G and li on the ends of the driving shaft, toothed wheel I on one end of the lower roller of the pair of rollers A and B, toothed wheel J on one end of the upper roller of the pair of rollers O and D, said toothed wheels I and J intermeshing, and wheel I intermeshing with pinion G, toothed wheel K on one end of the lower roller of the pair of rollers C and D, and toothed wheel L on one end' of the upper roller of the pair of rollers A and B, said wheels K and L intermeshing, and Wheel K intermeshing with pinion H, substantially as shown and described.

In testimony whereof we have signed our names to this specification in the presence of Ioo two subscribing witnesses.
